Enhanced self lift ZETA converter for negative-to-positive voltage conversion

In this paper, the ability of an enhanced self lift ZETA converter (also is termed simplified positive output LUO self lift converter) for negative-to-positive voltage conversion is investigated. It is shown that this converter can provide an effective path for negative to positive polarity inversion. Also an isolated type of this converter is introduced. This converter has some advantages in compare with a multiple lift CUK converter in number of circuit elements and an enhanced self-lift CUK converter in voltage transfer gain with the same duty ratio.
